Development of environmental friendly bioinoculate for peanut (Arachis hypogea L.) production in Eastern Ethiopia
Background: Bacterial bioinoculate is one of environmentally friendly input for crop production. Several works revealed that effectiveness of Rhizobium bioinoculant have been affected by the native rhizobia population. Hence, this study was initiated to evaluate the effect of selected Bradyrhizobium in nodulating peanut in the major growing areas of Ethiopia. Methods: The effect of eight effect...
متن کاملAssociation of nitrogen fixation to water uses efficiency and yield traits of peanut
mprovement of N2 fixation might be an effective strategy in peanut breeding for high yield under drought stress conditions. However, under water limited conditions peanut varieties having high water-use efficiency (WUE) are favorable. A pot experiment was conducted under greenhouse conditions at Khon Kaen University, Thailand during December 2002 to May 2003, and repeated during June 2003 t...
متن کاملImpact of Elevated CO2 on Tobacco Caterpillar, Spodoptera litura on Peanut, Arachis hypogea
If the carbon dioxide (CO(2)) concentration in the atmosphere changes in the future, as predicted, it could influence crops and insect pests. The growth and development of the tobacco caterpillar, Spodoptera litura (Fabricius) (Noctuidae: Lepidoptera), reared on peanut (Arachis hypogea L.) foliage grown under elevated CO(2) (550 ppm and 700 ppm) concentrations in open top chambers at Central Re...
متن کاملNitrogen Nutrition and Xylem Sap Composition of Peanut (Arachis hypogaea L. cv Virginia Bunch).
The principal forms of amino nitrogen transported in xylem were studied in nodulated and non-nodulated peanut (Arachis hypogaea L.). In symbiotic plants, asparagine and the nonprotein amino acid, 4-methyleneglutamine, were identified as the major components of xylem exudate collected from root systems decapitated below the lowest nodule or above the nodulated zone. Sap bleeding from detached no...
متن کاملDynamic Succession of Soil Bacterial Community during Continuous Cropping of Peanut (Arachis hypogaea L.)
Plant health and soil fertility are affected by plant-microbial interactions in soils. Peanut is an important oil crop worldwide and shows considerable adaptability, but growth and yield are negatively affected by continuous cropping. In this study, 16S rRNA gene clone library analyses were used to study the succession of soil bacterial communities under continuous peanut cultivation. Six libra...
